  <p>The copy_n() function copies <em>num</em> elements starting at
  <em>from</em> to the destination pointed at by <em>to</em>. To put it
  another way, copy_n() performs <em>num</em> assignments and
  duplicates a subrange.</p>

  <p>The return value of copy_n() is an iterator that points to the
  last element that was copied, i.e. (to + num).</p>

  <p>This function runs in <a href="../complexity.html">linear
  time</a>.</p>
